Background: The Anterior Cruciate Ligament-Return to Sport after Injury (ACL-RSI) scale is widely used after anterior cruciate ligament reconstruction (ACLR), but its 3 subscale domains of emotion, risk appraisal, and confidence are rarely considered when assessing readiness to return to sport (RTS). Current guidelines for ACL-RSI scores at time of RTS are derived from adult-only studies, and there is a need for age- and sex-specific data to guide RTS decision-making.
Purpose/hypothesis: The purpose of this study was to investigate differences in ACL-RSI subscale scores by age and sex.
Isokinetic Knee Strength and Patient-Reported Outcomes Differ Between Graft Types in Adolescents After Anterior Cruciate Ligament Reconstruction: A Multicenter Study.
Orthop J Sports Med
May 2025
Background: Graft selection can influence strength and patient-reported outcomes (PROs) in adults undergoing anterior cruciate ligament reconstruction (ACLR). Yet, there is a lack of high-quality evidence comparing these results in adolescents.
Purpose/hypothesis: The purpose of this study was to determine differences in quadriceps and hamstring strength and PROs between adolescents with bone-patellar tendon-bone (BPTB), quadriceps tendon (QT), and hamstring tendon (HT) autografts.
Background: Social determinants of health (SDOH) contribute to delays in access to care and inferior outcomes following anterior cruciate ligament (ACL) reconstruction. The interplay between multiple SDOH factors has not been investigated in children and adolescents during rehabilitation.
Purpose: To assess the relationships between SDOH variables, including demographics, singular surrogate indicators and multivariate indices, and quadriceps strength recovery at time of return-to-play testing following pediatric ACL reconstruction.
Comparison of Muscle Activity During a Ring Muscle Up and a Bar Muscle Up.
Int J Exerc Sci
December 2023
Article Synopsis
- The muscle up (MU) is a complex gymnastics move combining a pull up and a dip, and can be done on a bar (BMU) or rings (RMU).
- This study aimed to compare muscle recruitment in specific upper body muscles during BMU and RMU among ten active males.
- Results showed that RMU required greater muscle activation in certain muscles (upper trapezius, biceps, and forearm flexors during pull phase; triceps and biceps during push phase), indicating that RMU is more challenging than BMU, which may be a better starting point for beginners due to its lower difficulty.
Background: Previous research has demonstrated the benefits of both stabilization and non-stabilization of the scapula during stretching in individuals with posterior shoulder tightness, but limited evidence exists in patients with shoulder pain.
Hypothesis/purpose: The aim of this study was to determine the effect of stabilized scapular stretching on patients with shoulder pain. The primary hypothesis of this study is that stabilized scapular stretching will improve glenohumeral motion and pain compared to non-stabilized stretch program.
Line Hops and Side Hold Rotation Tests Load Both Anterior and Posterior Shoulder: A Biomechanical Study.
Int J Sports Phys Ther
April 2021
Background: Clinical tests should replicate the stressful positions encountered during sport participation. Evaluating the kinetic and electromyographical demands of clinical tests enables clinicians to choose appropriate tests for specific sports.
Purpose: To describe the shoulder forces and muscle activation levels during closed chain functional tests of Line Hops (LH) and Side Hold Rotation (SHR).
